4provided on its periphery with suitable charging and dumping doorsarranged onl one longitudinal oline, together with longitudinallydisposed baiiles arranged on the inner 4wall and cut atsuitable pointsby spirally arranged baliies which converge toward the doors to bringabout the collection and concentration of the mass toward the doors tofacilitate the discharging operation, the direction of rotation of thebarrel being such that this collectionor concentration is brought aboutby these converging bailes.

The invention also relates to the arrangement of foraminous, fibrousmaterial on the inner wall between the baffles for supporting a suitablefiltering medium or cloth, the object of utilizing the fibrous materialbeing to provide a chamber or space for the collection of the liquorpassing through the filtering medium, the liquor being collected fromthis chamber in any suitable manner.k

The invention is an improvement upon the structure illustrated anddescribed in my patent for barrels, No. 1,215,565, granted February 13.1917. e

'1`he invention may be further briedy summarized as consisting in theconstruction and combination of parts. hereinafter set forth in thefollowing description, drawings and claims.

Referring to the drawings, Figure 1 is a view partly in elevation andpartly in vertical section showing the device; Fig. 2 is a horizontalsection looking upward toward the discharge doors; Fig. 3 is a sectionupon the line 3-3 of Fig. 1; and lFig. 4 is a section upon the line 44.

1n carrying out the invention any preferred type of barrel may beemployed so long as it possesses the necessary characteristics, but 1have shown one embodilnent which is eiective, and it will now bedescribed.

Supported on any suitable masonry setting are bearings 1 and 2 whichreceive hollow trunnions 3 and 4 respectively, the former preferablyforming a part of a barrel head 5 and having at its outer end a suitablegas or fiuid pressure connection 6, the other hollow trunnion 4 forminga part of a barrel head 7, and Within the bearing 2 provided withopenings 8 through the wall for a purpose to be described. Each of thetrunnions is provided with an inwardly extending flange 9, and theseflanges receive the barrel casing in this instance made up of staves orboards 10 braced and held throughout the length by suitable straps 11. The heads are held against endwise displacement by suitable rods 12secured in the heads in any obvious manner, no connection of the headsbeing shown, however, but the arrangement being one which is ordinarilyemployed in such construction.

0n one longitudinal line in the periphery or shell, suitable openings 13are provided, and these openings provideaccess to the barrel. lEach ofthe openings 13 is closed by a. suitable door construction. and eachcornprises a cast door 14 pivotally mounted upon a bar 15 in turnpivotally connected to a pair of links 16, these links being in turnpivotally connected to suitable ears formed on a ring 17 connected tosuitable straps 18 passing around the barrel. The other end of the bar15 is provided with an open-ended slot 19 extending inward from the end,and this slot receives a bolt 20 having an eye 21 engaging a pin 22carried by the ring 17. A suitable nut 23 engages the threaded shank ofthis bolt and serves as a means for holding the bar in position With thedoor closed. The door 14 is provided with a suitable lining 24 fittingnicely into the opening 13 in the shell.

'llhe staves or boards 10 forming the shell or casing are notched neareach end to form internal annular grooves 25 and the groovecorresponding to the head 7 'receives a suitable head lining 26 which isspaced from the head by suitable spacing strips 27. '1`his head closesthe opening in the hollow trun- Secured to the inner wall of the barrel,extendinl longitudinally thereof and spaced around t e periphery arepairs of strips or cleats 31. These strips are spaced from each otherand they receive between them .the folded portion 32 of a filter cloth-or medium 33, the folds 32 being held between the cleats 31 by bafliestrips 34 wedged into the notch formed by the fold, as is clearly shownin Figs. 3 and 4. lThese baffle strips 34 extend inward for a shortdistance and serve to agitate the material which is in the barrel whenit is rotated. Between adjacent pairs of strips or cleats 31 are mats orplates 35 of fibrous material, such as cocoa matting, and these mats orstrips'serve to hold the filter cloth or medium away from the internalperiphery of the shell or casing and thereb form chambers for receivingthe liquor fi terin through the filter medium. These ,cham ers aredrained by ports 36 extending radially through the wall andcommunicating at various points throughout the length ofthe barrel witha discharge manifold pipe 37. This pipe 37 at'the right end of thebarrel, as shown in Fig. 1, or at the-end corresponding to the head 7extends tothe center through one of the openings 8 into the opening ofthe hollow trunnion 4. There is a manifold discharge pipe for each ofthe longitudinal chambers formed by the bailes 34, and these severalpipes pass through the opening in the hollow trunnion 4 to any suitablepoint where the liquor may be collected therefrom.

It will be seen from the foregoing construction that after the materialis charged into the barrel and the doors are closed, pressure issupplied throughthe connection 6 and the barrel is set in motion, withthe result that the material is agitated and at the same time the fiuidpressure serves to drive the liquor from the material through the filtermedium into the chambers formed by the 'cocoa matting, from whence theliquor passes through the discharge manifolds out through the hollowtrunnion 4. This agitating and filtering operation is conductexd for theproper length of time and after it is completed and all of the liquorhas been withdrawn, ressure is supplied to the discharge' manifold ipes37, and the cake, which has collected upon the inside of the filteringmedium, is released or loosened up from the filter cloth or medium.- Theapparatus is then ready to be charged.

In order to facilitate the discharge of the material lthrough theopenings 13, I provide collecting .or concentrating baflles 38 whichextend spirally in two directions toward the doors, as shown, in Fig. 2.These bafiies cut the longitudinally disposed baflles and they serve tocause the material lto collect and p been discharged, the wetconcentrate toward the doors and to pass Aout as the doors move towardthe bottom in the rotation of the barrel. In this way the cake loosenedfrom the filter .cloth or medium is quickly discharged from -the barrel.After operation and after the material has filter cloths hang looselyfrom the cocoa matting, as shown in Fi 3 and 4.

I avingdescribed my invention, I claim 1. An agitating barrel,comprising a hollow cylindrical body closed at one end and provided atits opposite end with communication to a source of fluid pressure, theinner surface of said body being provided with a series oflongitudinally extending baflies, a door in the wall of said bodvintermediate its. ends, and additional ba es converging spirally in bothdirections from the ends of the body' toward said door and intersectingthe longitudinally disposed batlles, said spirally arranged baiilesbeing adapted to collect they material and facilitate .its dischargethrough the door.

2. An agitating barrel, comprising a hollow cylindrical body closed atone end and provided at its opposite end with communication to a sourceof fluid pressure, the inner surface of said body being provided with aseries of longitudinally extending bafiies, filter sheets on the innerwall of said body extending from baffle to baille and supported therebyand forming with the inner surface of the wall of the body a series offiltrate receiving chambers, means for conducting the filtrate from saidchambers, a door in the wall of said body, additional bafiies conver ingspirally in both directions from the en s of said body 'toward saiddoor, said spiral ballies being adapted to collect the filtered materialand facilitate its discharge through the door when the body is rotated.

3. An agitating barrel, comprising a hollow cylindrical body closed atone end and at its opposite end provided with communication to a sourceof fluid pressure, the inner surface of said body being provided with aseries of longitudinally extending baffles, a plurality of doors in thewall of said body, and sets of converging spirally arranged baffles onthe inner surface of the body wall, one set for each door, said spirallyarranged baflles being adapted to direct the material toward said doorsand facilitate its discharge therethrough.

In testimony whereof I afi'ix my signature in presence of two witnessesas follows.
